Maybe shit is not worthless. Maybe we can mine some data outta that. We need to be smart about it though.

I am skeptical, whether spraying water at the butt is a good idea. What about the additional aerosols that creates? And if the spraying does not have the water pressure, you might end up with a dirty and wet butt, instead of only a dirty butt.

I also dislike toilets, which when you dump, allow water to splash up at you. I don't think that water is necessarily very clean.
